In reality, we have a 1GBit connection to the world via Hurricane Electric, but alas this is constrained by a 100 Mbit fiber coming out of the lab down to campus - it will take some big $$$ to upgrade that, which may happen sooner or later (as it would not only benefit us).

... We have gigabit all over our server closet (more or less - some older servers are 100Mbit going into the 1Gbit switch).

So, appears there's already fibre in place, but not the high speed connections.

I wonder which department is waiting for which department to provide the $$$?

It will be very interesting to find out what campus finds. Might not need to dig any trenches at all -- he says hopefully as Murphy stands menacingly just out side his field of view.

I mentioned how we seem to have a 60Mbit ceiling...

... We have gigabit all over our server closet (more or less - some older servers are 100Mbit going into the 1Gbit switch).

But I do remember quite clearly how Matt eventually found that the 60 MB cap was the internal processing limit of the CISCO routers then in use. Upgrading the routers got us to the effective 95 MB cap we have now.

If it is political, that there isn't better comms to the building, maybe we need to shame the 'powers that be' into action.
A few thousand e-mails from the us users might wake them up. Or ask the students to have a demonstration on our behalf.

I think if we want to have a "demonstration" it'd be best to mail in a $5 bill rather than try to "shame" the administration into spending more money on what is clearly an under-funded project flying under the radar.

The minimum donation the Berkeley system supports is 10 U.S. dollars. Mailing in a $5 bill would create a bureaucratic dilemma, that's the worst kind.

That $5 amount has been mentioned several times recently, it is certainly tempting to think in terms of how little each participant would need to contribute to make this a well-funded project. But the world seldom works as we would prefer, I'm just trying to keep the record straight so practicalities aren't forgotten.

$5 is a metaphor, I meant "donate."

I should know that when dealing with engineering-types that it is better to specify the amount to three decimal places.

Thanks to the team that keeps our crunchers fed with work. Here's my thought on the comment about turning downloads off. 1st Turn data recorders off, split the tapes that have just been filled with fresh data to save trashing data collected. Is the gigabit Internet connection a flat rate or is it a set rate per petabyte? from the Current Budget fall 2008 it says that to get a 1Gbit connection to the lab it will be $80000. I'm not sure if this is the connection that the lab can only use 100Mbit of.

SETI buys their bandwidth delivered to one of the internet exchanges (PAIX) so it is very inexpensive.

Campus takes care of delivering it from PAIX to SSL. The university-owned connection isn't gigabit all the way from PAIX to SSL.

Bandwidth is available second-by-second, 24 hours/day. Turning off uploads and downloads, or limiting them to certain days, is just wasting every second during those days.

Thanks for the updates. It looks like it will be months rather than weeks before a permanent corrective action can be in place for the bandwidth issue.

Meanwhile, is it possible for an interim solution? Even a 50% uptime wireless will help a lot with the frequent backlogs that take days to clear these days (since "normal" days the line is at least 80-90% utilised, and during recovery maybe 20% is available to clear backlogs). Or for that matter, since the "non-SETI" line up the hill is only using like 10mbits/sec or so, to have a throttled limit of SETI traffic to flow through it, like ~50mbits/sec will be of great help to the project.

Service to provide fiber connectivity to a department building that is outside of the main campus perimeter.

SSL is outside the main campus perimeter. Check the campus map.

This makes the $80,000 figure in the budget make sense.

I'm really not trying to call you out, or question you, nor do I work for IST or at the SSL.

The page says:

This is provided by Comcast on a case-by-case basis, depending on their ability to provide fiber in the vicinity of the building. If fiber is available, the cost will vary depending on the amount of construction (e.g. trenching, provisioning for conduit) required to get the fiber into the building.

I'm not sure, but I'm guessing based on Matt's posts, that Comcast does not have fiber near SSL.

Either way, Matt says that IST is doing the analysis to see what's available, and what is possible.

I also think that in general, Campus has treated SETI@Home pretty well. They've not only let them buy bandwidth off-campus (instead of forcing them to pay campus rates), but they've provided transport from PAIX to SSL.

You sound stressed, busy, and overly occupied. I have been in such positions, and yes, sometimes you need to pull the plug, reorganize, and come back on line with a refreshed vision, attitude, and better connection.

The constant demand that you push out work units can't possibly be healthy at all. Stop, reorganize, start stronger, begin anew with a better IT infrastructure, if that's what it takes, and you will be able to spend your days studying stellar clusters, instead of responding to complaints related to why 8500GT CUDA video cards overheat when they run version 36.09.09 vs version 36.09.10 graphic drivers...

Your dilemma is not a dilemma: you are trying to balance project participant's egos and complaints against real science; you are trying to please people that update that score daily, competitively so, against the real meaning of science behind the entire undertaking...You are in a sense engaging in a failing proposition, for the people crunching numbers on here could care less, if we discover a signal, they care much more about whether JoeBlo123's CUDA processor finished a workunit 5 minutes quicker than their SLI setup...

I don't envy you, it is a full time marketing job, or an HR job...However, while none of these number cruncher characters understand the statistics or the real science behind the enterprise, I can guarantee you, that they will be frustrated if their PC systems have nothing to do. And they will want to do something...They like SETI, it is part of them...

Shutdown for a month or two to upgrade your systems, do it. The people will return, for what you have going for you, is a most noble, exquisite, and promising enterprise, relating ONLY to what is the most fundamental and invigorating and puzzling question in our existence: " Are We alone"

P.S. I know the number crunchers aren't alone, or they think they aren't...I feel sorry for them...
